Dear all,
I have a pressure inlet whose values change (descend) with respect to time and after some time (say after 3 seconds) it completely stops which means there is no flow, but I have to continue the simulation to check the scales of heat transfer until time 10sec. How to implement this in the fluent? The case is 2D. thank you in advance. |

You can set a time-varying bc using a UDF in ANSYS Fluent. E.g. https://www.afs.enea.it/project/nept.../tg/node69.htm |
